TO ALL WHOM IT MAY CONCERN:

Be it known that I, Jo HN-P. s'M ITH, of Claverack,-in the county of Columbia, and State of New Yorl ,'have invented certain new and useful Improvements in'Shakers for Threshing-Machines; and Ido hereby declare that the following is a full, clear, and exact description of the same, reference being had to-the accompanying drawings, makinga portion of this specification, in which-- I Figure 1 is a longitudinal section of a shaker made according to my invention.

Figure 2 is aplau view of the same.

Similar letters of reference ind-icate corresponding parts in both figures.-

. "It is essential to the perfect operation of the shaker or endless carrier employed to convey thestrav;

from a. thresher, and to separate the grain from the said straw, that such shaker shalhhave a vibratory motion,

in addition to its continuous carrying-movement; 'and the object of this inveiition is to provide an efficient, strong, and durable means of producing'such vibratory motion.

The invention consists in so combining rotary shaking-armsivith theendless shaker or carrienas to com 'municate a vertical movement to the upper part of the shaker, thereby securing the ohj'ect mentioned.

The invention further consists in a novelarrang'ement of parts, wherebythe most efl'ective operation 'of the first-mentioned and principal feature of theinvention is secured. I i

To enahleothers to understand the construction and operation of my invention, I will proceed to describe it with reference'to the drawings. I 1 l A represents a framing of any-suitable construction, designed tobesecured in the ordinary orin any appropriate manner, behind the throsher, and the oflice of which is to support the endless shaker or'carrier'B, which may consist of endless belts, or, running over.appropriate'pulleys, b,'a.nd furnished, at suitable distances apart, with transverse bars or strips, 0, the shafts of the pulleys b'working in suitable bearings provided in the.

framing A, and one of the said shafts being'furn'ished arith a bandwheel, :1, whereby, throughthe agency of it suitable driving-band, the continuousmovement indicated by the arrow in fig. 1 may be communicated; to the shaker, to enable the same to carry away from the thre sher the straw deposited thereon from the said thresher.

Extending from one side of the framing A to the other, and between the upper and lower portions of the endless carrier B, is a transverse shaft, e, furnished at neof its outer ends with a pulley, a','driven by a belt, 6, from a pulley, 0', provided upon the corresponding ends of one of the shafts of the pulleys b; Securednear each of the ends of the shaft ejust mentioned, and preferably underneath the lateral or outermost of the belts a thereof, are two shaking-armgf, which, when the shai't e is rotated by the means hereirrbefore specified, alternately lift the uppermost portion of the carrier to the position represented in fig. 1, andallow the same to drop to the position shown in red outline, this vibratory or'up-and-down movement communicated to the shaker effectually shaking and separating the grain from the straw, as the 'latter is carriedback from the".'thresher by the continuous movement of the said carrieraround its pulleys b.

What I claim as my invention, and desire to secure by Letters Patent, is- 1. The rotating shaking-arms f, in combination with the endless carrier or shaker B, substantially as and for the purpose; specified. i p i i I 2. The arrangement of the shaking-arms transverse shaft e, endless carrier or shaker B, vand framing A, substantially as and for the purpose specified. JOHN 1?. SMITH.
